Help With 32 Heater Fan

[-Chris-]

hey guys.

before you say it. yes i did search these forums and a few others.

problem i have with my car is my heater fan wont turn off.

i thought it wouldnt turn ON but the plug on the fan was disconnected.

so when i press the fan speed button and set it to full it speeds up slightly.

but i can get the darn thing to turn off without unplugging it!

any ideas would be a great help. sorry if this has been covered but ive searched as much as i can and tried to nut it out myself for hours. most of my intereor is on the garage floor. knowing my luck its probably a relay, but im sure ive checked them all...

thanks in advance.

anybody?

It might be that the fan speed control resistors have shorted. There's an assembly that screws into the side of the fan housing unit 'behind' the glove box. It will have a 4/5 wire electrical connector attached and is usually held by a couple of screws. It has a series of 4 or so wire coils (resistors) which control fan speed. One or all might be shorted or just need cleaning. That's all I can think of.

thanks ill have a look tomorrow after work, its a bit dark out atm.

i dont suppose you have any pics? might help me locate it.

are you talking about the thing with the fins that screws into the white box thats right behind the glovebox? or into the fan itself?

No pics. It will be screwed into the fan housing or the box it feeds into. Will be held by a couple of screws and have an electrical connector. If you disconnect it and the fan is running it should stop.
